HENRY E. G. LUYTIES, OF NEV YORK, N. Y.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 366,732, dated July 19, 1887.

Application tiled May 24, 1887. Serial No. 239,190. (No model.)

To aZl whom it may concern.-

Be it known that I, HENRY E. G. LUYTIEs, a citizen of the United States, residing at the city of New York, in the county and State of New York, have invented a certain new and useful Improvement in Corks for Bottles, of which the following is a full, clear, and exact specification.

My invention relates to certain improvements in bottle-stoppers; and the object of my mospheric conditions, and consequently leak age will invariably take place at the joint formed between the neck of the bottle and the head of the cork. The purpose of my improvement is to overcome these disadvantages, and this I accomplish by the construction shown in the accompanying drawings, in which t Figure l isa vertical section of a stopper made according to my improvement shown applied to a bottle. Figs. 2 and 3 are side elevations of the two parts forming the stopper shown separated.

Let a, Fig. 1, represent the bottle-stopper as a whole, which is made of india-rubber or analogous substance combined with cork.

- This stopper is composed of the two parts b sists of the annular top or head (2, having the central stem, 0. The side or outer edge of the head is prolonged downward, so as to form an annular hollow neck part, (1, which is made tapering on its inner surface to make it conform to the taper of the neck of the bottle. The other portion of the stopper consists of a cylindrical piece of cork-wood hollowed out to form a socket, f, suitable to receive the rubber stem 0 of the body I). This case or covering 0, which incloses the stem, is closed at the bottom, so as to prevent any contact of the rubber with the liquid in the bottle.

On the under side of the head (I of the rubher body, and surrounding the stem 6, is formed an annular groove, g, which receives the upper edge of the cork casing c.

The rubber body I) is so formed that it [its tightly on the top edge of the neck of the bottle c, and extends over and around its side, enveloping the same like a snugly-fitting cap, packing the joint, which is necessarily formed where the head of the cork and top edge of the bottle meet. By this means leakage is entirely prevented.

The stopper may be wired in the bottle in the usual manner, if desired.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a bottle-stopper consisting of a body of rubber having a stem covered with cork and an annular neck part adapted to inclose the neck of the bottle, as set forth.

2. A bottlestopper consisting of a rubber body provided with a. central stem and having an annular recess surrounding said stem adapted to receive the neck of the bottle, and a cylindrical cork provided with a socket to receive said stem, as set forth.

3. The combination of the body b, having extended and tapered side portion, (1, and stem 6, with the cylindrical -cork piece 0, provided with socket f, as set forth.
